insiz'e, some being iiitehded'i the ceiling level. It spreads out across the ceiling and, as the further discharge of heated air occurs, and the coolest air is drawn from the room in which the. cabinet is installed and from the adjoining rooms connected with it by the usual door-ways, the entire body of warmer air in each room settles. The heated air flows from the room in which the cabinet is located through the doorways into the adjoining rooms, where it rises to the ceiling and takes the place of the coolest air withdrawn along the floor level by the suction created at the intake opening 3 in the cabinet. In this way several rooms are kept warm With a single heating unit, such as that shown in Fig. 1.

If desired, fresh air may be led in from out of doors through the duct or conduit l8, Figs. 1, 4 and 6, which opens into the lower chamber in the cabinet and this supply of air can be controlled by a damper or shutter 20 operated by the knob 2|. In very cold weather such inflow of air ordinarily Will not be used.

' This outside supply of air, however, is useful in summer when air may be taken from the cool side of the house, or from an enclosure built especially for the purpose and can be drawn in and circulated by means of the fan l2, the heating unit at this time being cold or unwarmed. And this cooling effect can be materially improved by circulating a cool brine or other heat absorbing medium through the unit 5, thus serving to modify very substantially the indoor temperature.

In the latter event, it will be preferable to draw air from the upper part of the room through the opening 4 and to discharge it through the lower opening 3 which normally serves as'an air intake. Partly for this purpose, and also to facilitate inspection and repairs, the fan is so supported as to be easily withdrawn from the cabinet. As best shown in Figs. 2, and 4 to 6, a drawer-like construction is provided for this purpose. That is, the fan is mounted on a transverse beam 22 of channel section, the ends of which are welded to channel-shaped slides 2323 running on stationary bars 24-24 in essentially the same manner that the filter I4 is supported. These channels 23 also are welded to the front face plate section 25 which extends entirely around the opening 4. Consequently, this whole fan unit, or assembly, including its support and its motor, can be withdrawn from the cabinet, whenever desired, as for inspection or repairs.

In order to permit this unit to be placed in the bottom of the cabinet, as above indicated, another slide containing the inlet opening 3 and including the same kind of a frame structure used in the fan slide, is provided at the bottom of the cabinet and is shown at 26. It includes channel bars 23', Fig. 4, running on stationary bars 24, and this lower drawer or slide is made of the same dimensions as the corresponding parts of the fan slide, so that when the latter is removed it can be substituted for the lower slide 26, and the latter can be installed at the top of the cabinet. In other words, the two are interchangeable. This is very desirable when a cooling medium of any kind is circulated through the unit 5.

When it is desired to use a heating unit of this 4 character, not only to heat the rooms on the lower floor, but also one or two in a floor above it, such an arrangement as that shown in Figs. '7 and 8 may be employed. Here a duct or conduit 21 is connected at its lower end with the port or outlet 28, Fig. 6, of the cabinet 2 and is led upwardly through the ceiling of the room below to a point close to the ceiling in the room above. At the upper end of this conduit a casing is formed to take a fan unit like that shown in Fig. 2. 'In Fig. 8 this fan isshown at 30. Normally any flow of air through the port 28, Fig. 6, is prevented by a hinged plate or damper 3!, but when the upstairs connection 21 is used, this damper is turned into its open position, as shown in Fig. 8, where it is held by a latch 32, so that under these conditions the air heated in the cabinet 2 is divided, part of its being discharged into the room in which the cabinet is located and the remainder flowing upwardly through the duct 21 and being delivered by the fan 38 just below the ceiling level in the upper room.

The cool air in the latter room flows down through a register 33, Fig. 7, in the floor of said room and through a duct 34 which delivers it into the lower chamber of the casing or cabinet 2 at the side opposite the fresh air duct 18. This down flow of air may be controlled by a damper or shutter like that shown at 20, and operated by a knob or handle. Further control of the distribution of air between the upstairs and downstairs rooms may be afiorded by pivotally mounting the shutters on the fan unit and connecting them together, as by a rod 36, Fig. 2, so that by turning one, all of them will be adjusted to shut off more or less of the air discharged by the fan H2. The same construction will be provided to cooperate with the fan 30, and shutters so arranged may be used at the intake opening 3.

As shown in Figs. 5 and 6, the casing includes partition plates 38 and 40 which cooperate to form a chamber in which the motor I3 is housed; but the partition 38 is provided with an aperture through which the motor may be withdrawn. Normally this aperture is closed by a plate 4!, Fig. 5, rigid with the motor and its mounting.

The invention thus provides a heating unit which eliminates the necessity for the conventional radiators; simplifies the heating system; improves the efiiciency of that system; and distributes the heat to the areas at which it is needed with a high degree of uniformity. It can be used to modify the room temperatures not only by heating them, but also by cooling them, and with the aid of such supplemental ducts as those above described, the installation can be modified to accommodate the great variety of conditions found in diiferent homes. Moreover, with the form of the invention shown in Figs. 7 and 8, either the group of rooms downstairs or those on the second floor can be heated to the exclusion of the other, or both groups may be heated, as desired.

Having thus described my invention, what I desire to claim as new is:

1. An apparatus of the character described,

' comprising a casing constructed to extend sub- '5 and motor are-supported, said casing being provided with recesses near its top and bottom, in either of which said assembly may be mounted selectively to force air through said casing either up or down, as 'desired. I o ,7

2, An apparatus of the character described, comprising a casing constructed to extend substantially fro-nith'e floor to the ceiling of aroom and "provided with lateral air openings in its upper and lower end portions, a heating unit in said casing between said openings, said unit exposing a large area to contact with the air flowing from one o fusaid openings to the other, an air circulating assembly comprising a fan, a motor for driving said fan, a support on which said fan and motor are..-rnounted, said assembly being positioned in said casing substantially in alignment with one of said lateral openings to force air therethrough, and said casing having guides on which said support is mounted for the sliding movement of said assembly into and out of said casing.

3. An apparatus according to preceding claim 2, in whichflsaid air circulating assembly also includes a grill mounted on the support for said fan and motor" and adapted to fit snugly into the 6 opening in said casing with which said assembly is positioned to cooperate.
